Hello LindaA, thank you for your feedback. We're sorry to hear your paint was thicker than anticipated and didn't cover your surface as expected. Each gallon of our Premium Plus Paint covers about 250-400 Sq. Ft. Keep in mind that more porous or textured surfaces will soak in more paint. To ensure proper paint consistency, we recommend stirring your paint for 3-5 minutes before using it. To ensure proper coverage on a medium to rougher textured surface, such as orange peel walls, we'd recommend using a 3/8" or 3/4" nap roller. Customer satisfaction is important to us. Please feel free to reach out to our Customer Care team directly with any questions you may have or for assistance. Have a great day. -Joanna
